IL41050TFDE

Overview

The IL41050TFDE is an IsoLoop isolated CAN transceiver manufactured by NVE. It integrates a CAN transceiver with a capacitive isolation barrier, providing galvanic isolation between the logic side and the bus side. The device supports data rates up to 1 Mbps and operates within a temperature range of -40°C to +125°C. Key electrical characteristics include a wide common-mode transient immunity and robust protection against electrostatic discharge (ESD) and bus faults. The component is housed in a small outline integrated circuit package designed for surface mount applications.

Feature Summary

• Capacitive isolation technology offering high reliability and long life without degradation over time.
• Integrated protection features including thermal shutdown, short-circuit protection, and ESD resistance.
• Hardware-selectable silent mode for disabling the transmitter during debugging or specific operational states.

Applications

• Industrial automation systems requiring reliable CAN communication.
• Automotive electronic control units (ECUs) operating in harsh electromagnetic environments.
• DeviceNet networks in manufacturing and process control applications.

Procurement Notes

Verify the exact suffix 'FDE' against official NVE documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with your board's footprint and reflow profile requirements. Cross-reference the part number with authorized distributors to confirm current availability and lead times.

Selection Notes

Select this component when high-speed isolation up to 1 Mbps is required for CAN interfaces. Consider the IL41050 series for its compact size and robust fault protection compared to traditional optocoupler-based solutions. Evaluate the need for silent mode functionality if hardware-level transmitter disablement is necessary for your system design.

Part Context

The IL41050 series represents NVE's IsoLoop technology, combining CAN transceiver functionality with capacitive isolation. This family includes variants with different packages and temperature ratings, such as the SOIC-16 and QSOP-16 options. The IL41050TFDE specifically denotes a variant within this lineup, tailored for specific packaging and environmental conditions.

Replacement Considerations

Direct replacements may include other ISO7241C or SN65HVD230 variants, but verify isolation voltage ratings and pinout compatibility. Check datasheets for equivalent common-mode transient immunity and supply voltage ranges before substituting.
